Book Description
Examination of 5-foot sections of felled Fraser fir, Abies fraseri (Pursh) Poir., trees infested or killed by the balsam woolly aphid, Adelges piceae (Ratzeburg), revealed that the height of the first annual ring of aphid-caused redwood increased as the height of the trees increased. The number of red rings varied from two in a tree 5 inches in d.b.h. to five or six in all trees 9 or more inches in d.b.h., indicating that larger trees can sustain aphid attacks for longer periods before death than can smaller trees.
